覆晶式發光二極體封裝結構 Flip-chip LED package structure

本發明涉及一種半導體發光元件,特別涉及一種覆晶式發光二極體封裝結構。 The present invention relates to a semiconductor light emitting device, and more particularly to a flip chip light emitting diode package structure.

發光二極體因具有生產成本低、結構簡單、低能耗低污染、體積小及容易安裝等優勢被大量用於照明光源及顯示技術中。 Light-emitting diodes are widely used in illumination sources and display technologies due to their low production cost, simple structure, low energy consumption, low pollution, small size and easy installation.

Electrically connected N and P electrodes. In the flip-chip light-emitting diode package, the flip-chip light-emitting diode is fixed on the substrate by a conductive adhesive, and the flip-chip light-emitting diode electrode is connected to the corresponding electrode on the substrate. However, under normal circumstances, since the conductive adhesive flows along the N-electrode and the P-electrode having a large thermal conductivity, the N-electrode and the P-electrode are soldered to cause a phenomenon of creeping, thereby causing an easy relationship between the N-electrode and the P-electrode. A short circuit occurs, so that the flip-chip light-emitting diode structure cannot work normally, and the conductive adhesive exposed to the outside of the flip-chip light-emitting diode due to the creeping of the solder absorbs the light emitted from the edge of the flip-chip light-emitting diode, resulting in overlying The light-emitting diode has a reduced light extraction efficiency.

所述基板10由導熱性能及導電性能良好的金屬材料製成,呈平板狀。所述基板10中部形成有一凸起40。所述凸起40及基板10的縱截面均呈矩形。 The substrate 10 is made of a metal material having good thermal conductivity and electrical conductivity and has a flat shape. A protrusion 40 is formed in the middle of the substrate 10. The protrusions 40 and the substrate 10 have a rectangular cross section.

請同時參考圖2,所述反射杯20為中部內凹杯體,其具有高反射率的材料製成。所述反射杯20包括內壁21和底壁22。所述底壁22中部向上凸伸形成有圍繞所述凸起40的凸環221,所述凸環221的頂面與所述凸起40的頂面平齊,所述凸起40的頂面外露。所述反射杯20的外周緣與所述基板10的外側共面。 Referring to FIG. 2 at the same time, the reflector cup 20 is a central concave cup body made of a material having high reflectivity. The reflector cup 20 includes an inner wall 21 and a bottom wall 22. A convex ring 221 surrounding the protrusion 40 is formed in a middle portion of the bottom wall 22, and a top surface of the convex ring 221 is flush with a top surface of the protrusion 40, and a top surface of the protrusion 40 Exposed. The outer circumference of the reflector cup 20 is coplanar with the outer side of the substrate 10.

所述LED晶片30固定於所述凸起40頂面。在本實施例中所述的LED晶片30為覆晶式發光二極體結構。所述LED晶片30包括由金屬材質形成的一P電極31和一N電極32。所述LED晶片30通過導電膠60固定在於所述凸起40之上。 The LED chip 30 is fixed to the top surface of the protrusion 40. The LED chip 30 described in this embodiment is a flip chip type light emitting diode structure. The LED chip 30 includes a P electrode 31 and an N electrode 32 formed of a metal material. The LED wafer 30 is fixed over the bump 40 by a conductive paste 60.

所述凸起40的頂部表面積小於所述LED晶片30的P電極31和N電極32的底面積之和。 The top surface area of the bump 40 is smaller than the sum of the bottom areas of the P electrode 31 and the N electrode 32 of the LED wafer 30.

進一步的,一絕緣部50穿射在所述基板10中。所述絕緣部50由絕緣性能良好且具有反射作用的材料製成。絕緣部50自所述基板10底部延伸至所述凸起40頂面。所述絕緣部50具體包括一主體部51及自主體部51頂端延伸至所述凸起40頂面的一延伸部52。所述主體部51的寬度大於所述延伸部52的寬度,所述延伸部52的頂面與所述凸起40頂面平齊且外露。所述絕緣部50將所述基板10分隔為相互絕緣的一第一基板11和一第二基板12。所述絕緣部50將所述凸起40分隔為相互絕的一第一連接部41和一第二連接部42。所述第一連接部41與第一基板11連接並共同組成第一電極。所述第二連接部42與第二基板12連接並共同組成第二電極。所述第一連接 部41和第二連接部42外露出凸起40的上表面部分以連接LED晶片30的P電極31及N電極32。 Further, an insulating portion 50 is penetrated in the substrate 10. The insulating portion 50 is made of a material having good insulating properties and having a reflecting effect. The insulating portion 50 extends from the bottom of the substrate 10 to the top surface of the protrusion 40. The insulating portion 50 specifically includes a main body portion 51 and an extending portion 52 extending from a top end of the main body portion 51 to a top surface of the protrusion 40. The width of the main body portion 51 is larger than the width of the extending portion 52, and the top surface of the extending portion 52 is flush with the top surface of the protrusion 40 and exposed. The insulating portion 50 divides the substrate 10 into a first substrate 11 and a second substrate 12 that are insulated from each other. The insulating portion 50 divides the protrusion 40 into a first connecting portion 41 and a second connecting portion 42 which are mutually exclusive. The first connecting portion 41 is connected to the first substrate 11 and together constitutes a first electrode. The second connecting portion 42 is connected to the second substrate 12 and together constitutes a second electrode. The first connection The upper portion of the projection 40 is exposed outside the portion 41 and the second connecting portion 42 to connect the P electrode 31 and the N electrode 32 of the LED wafer 30.

在固晶過程中,先將LED晶片30固定於凸起40之上。所述LED晶片30的P電極31及N電極32通過導電膠60與第一連接部41或第二連接部42相連。因凸起40頂部表面積小於所述P電極31及N電極32底面積之和,因此所述P電極31及N電極32底部邊緣將超出所述凸起40的頂面邊緣。在本實施例中,由於所述凸環221為厚度很薄的一層反射材料,所述凸環221的頂部邊緣不超出P電極31及N電極32超出凸起40頂面邊緣的部分,也即所述P電極31及N電極32的底面邊緣也超出所述凸環221頂面邊緣。 In the die bonding process, the LED chip 30 is first fixed on the bump 40. The P electrode 31 and the N electrode 32 of the LED wafer 30 are connected to the first connection portion 41 or the second connection portion 42 through the conductive paste 60. Since the top surface area of the protrusion 40 is smaller than the sum of the bottom areas of the P electrode 31 and the N electrode 32, the bottom edges of the P electrode 31 and the N electrode 32 will exceed the top edge of the protrusion 40. In this embodiment, since the convex ring 221 is a thin reflective material, the top edge of the convex ring 221 does not exceed the portion of the P electrode 31 and the N electrode 32 beyond the top edge of the protrusion 40, that is, The bottom edges of the P electrodes 31 and the N electrodes 32 also extend beyond the top surface of the convex ring 221.

本實施例中,因基板10的中部設置有凸起40且LED晶片30與第一連接部41及第二連接部42接觸的P電極31及N電極32的邊界超出第一連接部41及第二連接部42的頂面邊界,所以通過導電膠60固定所述LED晶片30於凸起40時候,凸起40的邊緣可引導導電膠60在重力作用下沿其周緣往下流動從而使導電膠60填滿塗設於第一連接部41和第二連接部42與LED晶片30之間之外,溢出的導電膠60收容於凸起40週邊的凸環221處並與P電極31、N電極32接觸將其進一步固定。如此,避免了大量導電膠60因爬錫而造成LED晶片30的P電極31與N電極32發生短路。並且導電膠60流向凸環221處避免導電膠60包裹LED晶片30的週邊,從而提升出光效率。 In this embodiment, the boundary between the P electrode 31 and the N electrode 32 in which the protrusion 40 is disposed in the middle of the substrate 10 and the LED chip 30 is in contact with the first connection portion 41 and the second connection portion 42 exceeds the first connection portion 41 and the The top surface boundary of the connecting portion 42 is such that when the LED chip 30 is fixed to the bump 40 by the conductive adhesive 60, the edge of the bump 40 can guide the conductive adhesive 60 to flow downward along the circumference thereof under the action of gravity to make the conductive adhesive 60 is filled between the first connecting portion 41 and the second connecting portion 42 and the LED chip 30, and the overflow conductive adhesive 60 is received at the convex ring 221 around the protrusion 40 and with the P electrode 31 and the N electrode. 32 contacts further fix it. In this way, a large amount of the conductive paste 60 is prevented from being short-circuited between the P electrode 31 and the N electrode 32 of the LED wafer 30 due to the creeping of the tin. Moreover, the conductive adhesive 60 flows toward the convex ring 221 to prevent the conductive adhesive 60 from wrapping around the periphery of the LED chip 30, thereby improving light extraction efficiency.

如圖3所示,為本發明第二實施例所述覆晶式發光二極體的封裝結構,其與第一實施例中所述覆晶式發光二極體的封裝結構相似,其不同之處在於:所述反射杯20的內壁21上形成多個突起23,所述突起23的直徑相同且均勻的排列,可以理解的所述突起23直 徑不同且交錯排列於所述內壁21。這些突起23用於提升反射杯20的反射效率。 As shown in FIG. 3, the package structure of the flip-chip type light-emitting diode according to the second embodiment of the present invention is similar to the package structure of the flip-chip type light-emitting diode in the first embodiment, and the difference is different. In the inner wall 21 of the reflector cup 20, a plurality of protrusions 23 are formed, the protrusions 23 having the same diameter and uniform arrangement, and the protrusions 23 are understandable. The diameters are different and staggered on the inner wall 21. These protrusions 23 serve to enhance the reflection efficiency of the reflective cup 20.

如圖4所示,為本發明第三實施例所述覆晶式發光二極體的封裝結構,其與第一實施例中所述覆晶式發光二極體的封裝結構大體相同。其不同之處在於:所述反射杯20內填充有封裝膠體70,所述的封裝膠體70中包括有螢光粉。所述封裝膠體70覆蓋所述LED晶片30,用於保護所述LED晶片30免受如水汽、灰塵的侵害。 As shown in FIG. 4, the package structure of the flip-chip type light-emitting diode according to the third embodiment of the present invention is substantially the same as the package structure of the flip-chip type light-emitting diode according to the first embodiment. The difference is that the reflective cup 20 is filled with an encapsulant 70, and the encapsulant 70 includes phosphor powder. The encapsulant 70 covers the LED chip 30 for protecting the LED chip 30 from moisture, dust, and the like.
